Title (EN) SINGLE SIDED STRETCH BONDED LAMINATES, AND METHOD OF MAKING SAME
(FR) STRATIFIES COLLES PAR ETIRAGE MONOFACES ET LEUR PROCEDE DE FABRICATION
Abstract:
(EN) An elastic laminate capable of being rolled for storage and unwound from a roll when needed for use, includes an elastic layer selected from the group consisting of an array of continuous filament strands, an array of continuous filament strands with meltblown deposited on the continuous filament strands, and a film; and a facing layer bonded to only one side of the elastic layer. The laminate may also include an adhesive that demonstrates a relatively short open time deposited between the elastic layer and facing layer, or such adhesive and a postbonding adhesive or nonblocking agent, or a nonblocking agent layer deposited on the elastic layer on a side opposite to the facing layer. The meltblown layer may include an elastic polyolefin-based meltblown polymer having a degree of crystallinity between about 3% and about 40%. The laminate suitably has an inter-layer peel strength of less than about 70 grams per 3 inches cross-directional width at a strain rate of 300 mm/min. Alternatively or additionally, the continuous filament strands and/or the facing layer may include an elastic polyolefin-based meltblown polymer having a degree of crystallinity between about 3% and about 40%. In certain embodiments, the elastic laminate may include an extensible facing layer bonded to an elastic or semi-elastic film layer having a basis weight of about 50 gsm or less, wherein the facing layer includes an elastic polyolefin-based polymer having a degree of crystallinity between about 3% and about 40%.
(FR) L'invention concerne un stratifié élastique pouvant être enroulé en vue d'un stockage et déroulé à partir d'un rouleau en vue d'une utilisation. Ce stratifié comprend une couche élastique choisie dans le groupe constitué par un ensemble de filaments continus, un ensemble de filaments continus sur lesquels une couche de fusion-soufflage est déposée, et un film, ainsi qu'une couche frontale collée à une seule face de la couche élastique. Le stratifié peut également comprendre un adhésif présentant un temps ouvert relativement court déposé entre la couche élastique et la couche frontale, ou cet adhésif et un adhésif de post-collage ou un agent non bloquant, ou une couche d'agent non bloquant déposée sur la couche élastique sur une face opposée à la couche frontale. La couche de fusion-soufflage peut comprendre un polymère de fusion-soufflage à base de polyoléfine présentant un degré de cristallinité compris entre environ 3 % et environ 40 %. De préférence, le stratifié présente une résistance au pelage intercouche inférieure à environ 70 grammes par 3 pouces de largeur transversale à une vitesse de déformation de 300 mm/min. Selon une autre variante ou dans un mode de réalisation supplémentaire, les filaments continus et/ou la couche frontale peuvent comprendre un polymère de fusion-soufflage à base de polyoléfine élastique présentant un degré de cristallinité compris entre environ 3 % et environ 40 %. Dans certains modes de réalisation, le stratifié élastique peut comprendre une couche frontale extensible collée à une couche de film semi-élastique présentant un poids de base inférieur ou égal à environ 50 g/m2, la couche frontale comprenant un polymère à base de polyoléfine élastique présentant un degré de cristallinité compris entre environ 3 % et environ 40 %.
